چکیده Land use is being considered as an element in determining land change studies, environmental planning and natural resource applications. The earth’s surface study by remote sensing has many benefits such as, continuous acquisition of data, broad regional coverage, cost effective data, map accurate data, and large archives of historical data. To study land use / cover, remote sensing as an efficient technology is always desired by experts. In this case, classification could be considered as one of the most important methods of extracting information from digital satellite images. Selecting the best classification method and applying the proper values for parameters extremely influences the trust level of extracted land use maps. This research is an applied study which attempts to introduce Support Vector Machines (SVM) classification method, a recent development from the machine learning community. Moreover, we prove its potential for structure–activity relationship analysis on Aster multispectral data of the central county in the Kabodar-Ahang region of Hamedan, Iran. Accuracy of SVMs method is varied by the type of kernel function and its parameters. The purpose of this research is to find the accuracy of land use extraction by SVM method using a Polynomial and radial basis functions kernel with their estimated optimum parameters in addition to comparing the results with Maximum Likelihood Method. Most of the scientists imply that Maximum Likelihood Method is suitable for classification. Therefore, we try to compare SVM with ML method and to deliberate the efficiency of this new method in classification progress on Aster multispectral data. The accuracy of SVM method by Polynomial and radial basis functions kernel with optimum parameters and ML classification methods achieved 93.18%, 91.77% and 88.35 % respectively. By comparing the accuracy of these methods, SVM method by Polynomial kernel was evaluated as suitable. Therefore, we can suggest using SVM method espec
